There are apparently no endemic Aphidae in Hawaiia. In a recent paper (1907, 

 P. H. E. S. I. pp. 99—102), I recorded four species, viz.: Myzus ciiricidus Kirkaldy, 

 Aphis rosac (Linn.), Loxerates saccJiari (Zehntner) and Myzocallis kahaivaluokalani 

 Kirkaldy. Aphids on Sorghum, Sonchiis, Hibiscus and Cabbage, have not been studied 

 sufficiently fully yet, and I recently found another species at Kilauea, Hawaii, on 

 grasses etc. All these are probably introduced. 



Fam. ALEYRODIDAE. 



Six species of Aleyrodes, none apparently endemic, have been enumerated by 

 Kotinsky in my recent Catalogue of this family (1907, Bull. Board Agric. Hawaii 11.), 

 viz. : giffardi, hibisci, kirkaldyi and sonchi of Kotinsky, vaporariorum Westwood, and 

 an unnamed species on Coffea. 



Fam. COCCIDAE. 



Since the first part of this contribution was published, (huj. op. iii. pp. 102 etc.), a 

 revised list has been issued (1904, Entom. xxxvii. pp. 226 — 30, with a bibliography), 

 totalling 53 species, a net increase of five.
